Subsea Hydraulic Coupler

Wave-SubseaDesignAS

HYDRAULIC COUPLER WITH EXCELLENT FLOW PROPERTIES

With SubseaDesign’s hydraulic coupler it is possible to pressure test to full system working pressure against the retracted coupler without the need for an additional test cap. Due to the compact design and self sealing abilities of both sides of the coupler, ingress from sea water is confined to a minimum.

The couplers are fully DNVGL design approved and qualified to 3000 m (10.000ft) water depth.

The connectors can be applied on subsea wellhead connectors, riser connectors, emergency disconnect packages, quick release stab plates and emergency disconnect points.

These state of art couplers tolerates high angle interconnection and allows for both front and rear loading into hubs.
